I'm trying to learn about these engines as much as I can. That said, there's still a million things I don't know about Northstars. I've been looking for a chip that will work with an OBDI Northstar. I came in contact with a company and here's what they sent me. I have no idea what it means, or if it would even work in my car. Any help/insight appreciated. Here's what they sent me.

This is the description of the memcal pack:
It is to be used in a factory 93-95 OBDI ECM. It is engine management only. There is no torque management, nothing to degrade power. It is designed to run with a manual tranny and there are no shift functions whatsoever. The chip must be used with a 95 or earlier idle speed motor (ISM) throttle body. There is no Pass KeyII, all emissions work and must be utilized or it returns a check engine light. However, I blocked off my EGR valve, so it doesn't really do anything. The program uses two O2 sensors, one for each bank and is wired up as a 95 N*. The rev limiter has been reprogrammed to 6400. There is no TCC (traction control) and all diagnostic work and can be read with either a Tech 2 or the dash from a 95 or earlier car. What doesn't work is the A/C fast idle. It can be tricked by sending a PS low pressure signal in but this involves some minor work. It works in a Fiero with out any serious problems and is no harder to wire up than a 3800SC. The computer will even mount behind the seat in the standard location, but it is tight.
